This is really strange. I go to Settings > Messages and am presented a "Enter Apple ID" screen. I sign in with my email address and Apple ID password. I KNOW my Apple ID login info is correct but my iPad keeps telling me 'The user name or password for 'email@example.com" was incorrect. Try again".
How can this be? I even assured it was correct by using it on my iMessage on my iMac & MacBook. It is the correct login and password. I also logged out of my iTunes/App Stores and relogged back in with my Apple ID and password and it worked.
This is the second issue I've had with my iPad. Yesterday I tried to get the new Amazon Instant Video player to work and it would not. I wrote it off as a problem with THEIR app. But now I wonder if it isn't something going kooky with my iPad.
So, there's my problem. Anybody out there have a solution? I do not want to create another Apple ID.
